Toshiba today announced that samples of two new large capacity nearline hard disk drives (HDDs) are available now.

The 3.5-inch 7,200 rpm MG Series includes both SATA and SAS versions, "MG03ACA400" and "MG03SCA400" respectively, that deliver 4TB of storage, the largest capacity yet offered by Toshiba. The company is also offering samples of lower capacity models in each series.

Both the MG03SCA400 series and MG03ACA400 series support a sanitize overwrite function that allows IT administrators to write a predetermined data pattern across the entire user storage area on the disk, effectively erasing all previously written data. The sanitize overwrite operation can be performed before re-allocation, redeployment or retirement of the storage device.
